This little application lets you calculate the resonance frequency of a Helmholtz resonator in a serial configuration or plugged on a duct.

It is mainly useful for NVH engineer working in the automotive industry, to set the dimensions of an air intake system and his acoustic devices, in a NVH point of view.

You can either set a frequency target to calculate the right length, volume or diameter of your acoustic sub system or estimate the resonance frequency by filling the geometric properties.
